So he made them a feast, and they ate and drank. 31 In the morning they rose early and exchanged oaths. And Isaac sent them on their way, and they departed from him in peace. 32 That same day Isaac's servants came and told him about the well that they had dug and said to him, “We have found water.”
During the course of reading Genesis 26 we find most people coming to Isaac in conflict and all walking away in peace. Isaac was a peacemaker. Whatever you were looking for when you went looking for Isaac, it appears you always walked away from him with peace. Even here, we find him preparing a feast and making promises of peace to people who have done nothing but harass him previously. Isaac was often ready to forgive and quick to act if asked to give it.
